AfterHVAC Company in Marietta, GA
Most HVAC service calls in Marietta involve heat-pump systems and attic ductwork that were installed during Cobb County’s building boom between the 1970s and 1990s. We’re Brandt HVAC, and we specialize in the exact problems these aging systems develop: refrigerant leaks in heat pumps working against 140°F attic temperatures, degraded flex duct that’s crimped or disconnected after 30-plus years, and mismatched equipment that was never properly commissioned in the first place. You can reach us anytime at (984) 538-9003; a live person answers, day or night.
Why Marietta Homes Are Different
Marietta sits in the Georgia Piedmont at roughly 1,000 to 1,100 feet elevation, and that elevation doesn’t cool the summers. From June through September, dewpoints regularly hit the low 70s°F, which means your system isn’t just fighting temperature, it’s fighting moisture. An undersized or poorly charged heat pump will hold the thermostat setpoint and still leave you clammy. That’s the latent load problem, and it’s the single most common comfort complaint we hear in neighborhoods from Shallowford Falls to the Murdock Road corridor.
The housing stock tells the rest of the story. Brick-front ranches and split-levels built from the 1970s through the 1990s dominate, nearly all with flex ductwork routed through unconditioned attics. Cobb EMC pushed all-electric heat pumps hard during that era, so most of these homes never had gas furnaces installed. After three or four decades, that original flex duct has often degraded, its vapor barrier torn, connections separated at the plenum. In East Cobb subdivisions built between roughly 1983 and 1998, we also find two-stage and multi-zone systems that were wired or commissioned poorly during the construction rush, a 3-ton air handler paired with a 2.5-ton condenser, zone dampers bypassed entirely. These aren’t wear-and-tear problems. They were baked in from day one.
Pre-1950 homes near Marietta Square present the opposite challenge: tight spaces, no existing duct infrastructure, full retrofits that require creative equipment placement and custom fabrication.
Our Main Marietta Services
Most calls we get from Marietta homeowners fall into three categories: cooling failure during peak humidity, heating problems during ice-storm outages, and preventive maintenance to catch duct and refrigerant issues before they become emergencies.
AC Repair in Marietta
AC repair in Marietta almost always means heat-pump repair, and the diagnostic priorities are different here than in gas-furnace markets. We check refrigerant charge first, because attic duct leakage pulls hot, humid air into the system and can mask as a refrigerant problem. We inspect the flex duct for disconnections and vapor-barrier degradation. And we verify that the indoor coil and outdoor unit are actually matched, because mismatched equipment from the original install is common in Walton and Lassiter High School zone neighborhoods. AC Repair in Marietta covers our full diagnostic and repair process.
Furnace Repair in Marietta
Furnace repair is less common in Marietta than in northern markets, but it’s not zero. Some homeowners have added gas furnaces as backup heat, and older homes near the Square may have original or retrofitted gas systems. When we do furnace work here, we’re often dealing with intermittent ignition failures or blower motor problems in systems that run only during the coldest weeks. The bigger issue is usually the heat-pump backup: when Cobb County ice storms knock out power, heat-pump-only homes have no heat at all. Furnace Repair in Marietta explains how we handle both gas systems and backup-heat assessments.
AC Maintenance in Marietta
AC maintenance in Marietta is preventive maintenance for heat-pump systems operating in extreme attic heat and high humidity. Our tune-ups focus on refrigerant level verification, duct integrity inspection, and electrical connection tightening, the three failure modes we see most often in this market. We also measure static pressure across the coil to catch restrictions from dust loading or degraded duct liner. For homes in the 1980s and 1990s subdivisions, we specifically check zone-damper operation and equipment matching. AC Maintenance in Marietta details what’s included and how we price it.

FAQs About HVAC Company in Marietta
We typically schedule same-day arrival for cooling failures during summer heat and heating failures during cold snaps. Our phones are staffed by a live person 24 hours a day, so you won’t wait in a callback queue. Call (984) 538-9003 and we’ll give you a specific arrival window.
Some East Cobb and historic district HOAs require advance notice for equipment changes or outdoor unit placement. We handle the documentation you need for approval, and we’ll note any HOA requirements when we schedule your install or major repair. For standard service calls, no HOA notice is typically required.
This is the most common comfort complaint we get in Marietta. High Piedmont humidity plus attic duct leakage often means your system can’t remove enough moisture. The fix is usually a combination of refrigerant charge verification, duct sealing, and static-pressure testing, not simply a bigger air conditioner. We diagnose the actual cause before recommending any equipment change.
